Steel weathering process

Steel weathering, often called "weathering" or "rusting," is a natural process where steel reacts with elements like oxygen and moisture in the environment. Over time, this interaction forms a layer of iron oxide, or rust, on the steel surface. This rust can protect the underlying metal from further corrosion if it forms a stable, protective layer. Weathering steel, used in architecture and bridges, is specially designed to develop this protective layer quickly, reducing the need for painting and maintenance. Essentially, it leverages natural oxidation to enhance durability and longevity of steel exposed to the elements.
